Which heart layer lines the inner chamber surfaces and is the innermost layer?

The inner lining of the heart chambers is the endocardium. This layer lines the surfaces inside the chambers and over the heart valves, providing a smooth, low-friction surface for blood flow and helping protect the underlying muscle. It is the innermost heart layer.

The other layers have different roles and locations: the epicardium covers the outer surface of the heart, the myocardium is the thick muscular middle layer responsible for contraction, and the pericardium is the sac surrounding the heart.
